[0002] With the continuous development of the industrial field, the application of large-diameter steel plate coils is becoming more and more widespread. In the construction process of sintering projects, flue gas ducts are made of steel plate coils with a large diameter of about 4.5m to 6.4m. Due to the large diameter, the production time is long, and installation and transportation are difficult. Most of the pipes are made on-site. Traditional construction processes often decompose a section of pipe into multiple steel plates for bending, assembly and welding. Large-diameter steel plate coils have a large unfolding area, a large number of steel plate splicing joints, and a large amount of welding. Due to their large deadweight, the ovality of the rolled tube is difficult to guarantee. This process has a large amount of welding, a lot of material loss, a large amount of labor resources, low production efficiency, and it is difficult to guarantee production quality. Therefore, it is necessary to develop a steel plate coil auxiliary device to meet current usage needs. Utility Model Content
